That's not really the case. You could be restricted from wearing rings for decoration and fashion, but this would not apply to a wedding band. Because a wedding band isn't a piece of jewelry, it's a symbol.
It's the same with religious symbols, you can be restricted from necklaces, but if there is a religious pendant on a necklace that's different, because it ceases to be merely jewelry, it's a symbol. For safety reasons (in limited situations) you might be require to tuck it inside your clothing or remove it for the duration of the safety concern.
